i' SPINNING DEVICE.

Application lediMarch', 1927. Serial No. 172,745.

This in vention relates to a musical spinning device, and particularly to that class in which rotatable tops emit sounds produced by the passage of air through apertures therein. lts object is to piovide an article of this character having means to maintain the base elements in vertical position, and other means to rotate, or spin them rapidly and to reverse the direction of rotation at intervals.

A further object is a means whereby tension is applied simultaneously to an assem bled group of the rotatable units.

@ther objects are, a novel winding ele# l ment and a casing therefor.

The foregoing and other features of the device will be fully described in the following specification and illustrated in the accompanying drawings, in which:

Fig. 1 shows a side view of a rotatable unit. f

Fig. 2 shows a top plan view of saine.

Fig. 3 shows an enlarged vertical section on the lin 3 3 of Figure 2. Tt illustrates the winding element, casing, and the spool therein contained.

Fig. 6 shows on a reduced scale, a side view of an assembly frame with the units mounted therein, and also illustrates the tension mechanism.

Fig. 7 shows a cross section on the line 7 7 of Figure 6.

Fig. 8 shows a top view of the elements illustrated in Figure 6. y

Fig. 9 shows an enlarged perspective view of an upper holding clip with a fragment of a winding element casing and a supporting rod.

Fig. 10 shows an enlarged fragmentarj,7 view of a slotted vtension spring.

Referringy first to Figure 6 of the drawings, the invention comprises a frame 10, open at the sides and having horizontal rods as seen at 11 and12 secured therein, and rotatable units as 13, 14,15 etc. removably mounted on the aforesaid rods by means of upper clips as that seen at 16 in Figure 7, and by lower clips as that shown at 17 in the same figure. l/Vinding element casings as those shown at 13, 19 etc. in Figure 6 are located on spindles as seen at 20, 21 etc. These casings are provided with upper and lower bearing busliings as seen at 22 and 23 in Figure 7. A pressure element 24 is slidably mounted iii the said frame. This element has lateral arms as seen at 25, 26 etc., andslotted springs as that shown at 27, and again, enlarged in Figure 10. These springs press upon the upper bearing bushings, the degree of pressure being regulated by means of hand wheels as that shown at 28. This pressure element is supported at its ends by the screw shafts 29 and 30 as seen in Figure 6, these being threaded through the bosses 31 and 32 and guided by end brackets as that shown at F in Figure 7. The screw shaftsV are pivotally mounted at the bottom, having retaining base flanges as that shown at 34. It will be seen that the turning of the hand wheels raises, or lowers the pressure element as desired.

Referrnig again to the upper holding clips; these are secured to the base caps of the winding casings as seen in Figure 9. The lower clips have two tongues each as may be seen at 35 and 36 in Figure 6. and may be removed by simply lifting off from the supporting rods.

The detailed construction of the rotating units will now be described; referring first to Figure 1 of the drawings. The unit here shown has a base element with tip 41 and with perforations in its side walls as shown at 42, 43 etc. Musical sound is produced by the passage of air through these perforations while the unit is in rapidfrevolution. vA spindle 21 issecured to the top of the base element and passes upward through the winding casing 19, vbearing bushings being provided as shown at- 22 and 23. A linger grip 44 is ailixed at the top of the spindle. n

A pull cord 45 with hand grip 46 is secured within the casing as seen in Figure 3, it being secured to a spool 47 which has flanges 48 and 49, and a central tube 50 which is tight ly secured to the spindle 21 by the screw 51. The central tube abuts the bearing bushings 22 and 23 as shown and maintains the casing in its correct position on the spindle. A bottoni cap 52 is screwed on to the casing 19, and to this cap is aiixed the upper holding clip 16. Y

Units of the type described may be assembled in the frame as seen in Figures 6, .7 and 8, they being supported by means of the upper and lower clips as shown, and further secured in adjustable tension by the element 24. Then so assembled,'they may be caused to Arotine grouped cords as seen at 53 and 5l in Figure 8. rFliese cords being pulled byrgrasping' the grip piece as that seenat ab, and

5 iirst pulling and then releasing, thus causing the spindles to revolve lirst in one Idirection and then in the opposite thereto, the cord which has the lirst been unsound, l oing Vre wound by the impetus given to the units.

l rlllie movement thus described produces a harmony of varying musical notes as the air passes through the several units.

Another form of winding element is shown in Figures 4 and 5, in which a rel5 tracting spring 60 is secured at its top to the spool flange as seen at 6l, and its bottom to the base cap as seen at 62. `When this spring is employed, it reverses the winding spool at the `end ot the pull and resimultaneously bv means oi Ythe "each terminatingV in a slotted lea-iE4 spring,VV

which leaf springs engage the casings of the several rotatable units and exert a pressure thereon, cords secured to the winding elements of the said rotatable units, and 70 means .to pull the said cords simultaneously.

'3. In a device of the character described, a rotatable sound producing unit comprising a hollow base element having perforations in the walls thereof, a vertical Y,spindle a 75 flanged spool secured to the said spindle, a casing enclosing thesaid spool, an adjustable lower cap on the said casing and a clip member attached to the said cap, a cord secured to the flanged spool, and means to 80 grip the free end ot the said cord, and means to support the whole in an upright position.
